To investigate the effects of high-load eccentric exercise on the ultrastructure of autophagy and the autophagy-related proteins Beclin1 and LC3II / I in rats.
Forty-eight SD male rats were randomly divided into control group (C, =8) and high-load eccentric exercise group (E, =40) after adaptive training. Group E was run downhill for 90 minutes on the running platform, and soleus muscles were collected at 0, 12, 24, 48 and 72 hours after exercise. Transmission electron microscopy was used to observe the ultrastructural changes of skeletal muscle autophagosomes. Western blot was used to detect the expressions of Beclin1 and LC3II / I protein. Immunofluorescence was used to observe the localization and content of LC3.
The number of soleus muscle autophagosomes in group E was increased at 0, 12 and 24 hours after exercise, and LC3 autophagic fluorescence was significantly increased (＜0.01), while autophagic fluorescence at 48 hours after exercise was still increased significantly (＜0.05). Beclin1 and LC3II / I expression levels were increased after high-load centrifugal intervention (＜0.05), and were peaked at 12 h〜24 h after exercise (＜0.01), and fully recovered at 72 h after exercise.
High-load eccentric exercise can induce ultrastructural changes in skeletal muscle autophagy and increase the expression of autophagy protein. The peak value appears at 12 hours after exercise. The above may be one of the reasons for the decline in skeletal muscle function caused by sports injury.

Sixty SD rats (male) were randomly divided into sedentary group (Sed), intermittent fasting group (InF) and exercise group (Exe), 20 rats of each group, intervention duration is 14 d and 28 d. Animals of InF group were fasted every other day, animals of Exe group underwent aerobic exercise on treadmill, the weight was recorded every week. The body fat mass was recorded by DEXA and then the fat mass index was calculated. The wet weight of bilateral soleus muscle was weighed and wet weight index was calculated. Immunofluorescence was used to detect laminin and light chain 3 (LC3), which reflect muscle fiber cross-sectional area and autophagosome respectively. Transmission electron microscopy was used to observe the number and morphology of autophagosomes. The expression levels of autophagy related proteins Unc-51 like kinase 1 (ULK1), LC3, sequest Intermittent fasting is superior to exercise in controlling the growth of body weight and body fat in rats. ? In terms of skeletal muscle autophagy activation, the length of intervention required for intermittent fasting (14 days) is shorter than aerobic exercise (28 days).

To improve treatment outcomes, we sought to create an individualized, susceptibility-driven therapeutic approach among our patient population, which is one of the poorest in the nation. It is medically underserved, minority-predominant and has high incidence of H pylori infection.
We compiled various factors involved in the antibiotic resistance of H pylori from literature. We then created a predictive model to customize therapies based on analyzed data from 2,014 H pylori patients with respect to several of these factors. The predictions of the model were further tested with analysis of patient stool samples.
A clear pattern of H pylori prevalence and antibiotic resistance was observed in our patients. We observed that majority of H pylori patients were women (62%) and over the age of 40years (80%). 30% and 36% of the H pylori patients were African American and Hispanic, respectively. A median household income of less than $54,000, past H pylori infection, previous use of certain antibiotics for any infection decreased the chance of eradication. Results of the stool testing were consistent with model predictions (90% accuracy).
This model demonstrates the predictive accuracy of H pylori infection and antibiotic resistance based on patient attributes and previous treatment history. It will be useful to formulate customized treatments with predicted outcomes to minimize failures. Our community attributes may contribute toward broad applicability of model for other similar communities.

In India, AYUSH systems of medicine have been promoted as an immune-protection strategy. Andrographis paniculata (Burm. F) Nees (AP) mentioned in Ayurveda has been widely used for treating sore throat, flu, and upper respiratory tract infections which may provide possible novel therapeutic approaches, exclusively targeting SARS-CoV-2 and its pathways.
The present work uses liquid chromatography-tandem mass spectrometry (LC-MS/MS) metabolomics and combination synergy analysis based on network pharmacology to mine multimode evidence to understand the possible mechanism of action, diseases association, protein-protein interaction and major pathways involved therein.
Metabolite profiling was performed by Agilent QTOF LC-MS/MS system. Network pharmacology analysis was performed by using functional annotation analysis based on databases like Binding DB, STRING, DAVID and KEGG for further data mining. Further combination synergy was evaluated using "neighbourhood approach" and networks were constructed through Cytoscape 3.
